In this case, the solvent used for coating is generally limited to low boiling point and highly volatile solvents, and there is no selectivity of solvent, and the photosensitive drum after coating is dried in a dryer to form a film. Ta.

を用いて行なっていた。In the conventional method of manufacturing photosensitive drums using the above-mentioned dip coating method, the temperature of the object to be coated is not controlled, so when coating a thick film, the solvent for the paint is generally limited to a solvent with a low boiling point and high volatility. I end up getting beaten up. When such a low boiling point and highly volatile solvent is used, the concentration of the paint tends to change, making it impossible to obtain a stable film thickness. Furthermore, when a high boiling point solvent is used, a thick film cannot be formed even if dip coating is performed using a paint at room temperature and an object to be coated at room temperature. Furthermore, when a paint using a high boiling point solvent is heated, it is difficult to control the temperature of the paint, the concentration tends to change, and the film thickness of the coated object becomes unstable. Drying after dip coating has generally been carried out using a device such as a dryer.
本発明の目的は前記課題を解決した感光ドラムの製造方

ものである。In order to achieve the above object, in the method for manufacturing a photosensitive drum according to the present invention, a heating heater is disposed inside the photosensitive drum, and while controlling the temperature of the photosensitive drum with the heating heater, the circumferential surface of the photosensitive drum is heated. The coating solution is applied by dipping.

る。In the figure, a photosensitive drum 2 is held by a drum fixing chuck 1. The drum fixing chuck 1 fixes and holds one end of the photosensitive drum 2 to prevent the coating liquid from entering the inside of the drum, and also adjusts the amount of air inside the drum to prevent air leakage from inside the drum. A method of holding the photosensitive drum 2 is disclosed in Japanese Patent Application No. 63-35590.

ートで被覆しである。In the present invention, a film-shaped heater 4 is attached along the inner peripheral surface of a photosensitive drum 2 held by a drum fixing chuck 1, and a temperature sensor 3 for measuring the temperature of the photosensitive drum 2 is installed. The heater 4 is covered with a Teflon sheet having good solvent resistance.

塗布する。The present invention detects the temperature of the photosensitive drum 2 with a temperature sensor 3, adjusts the heat capacity of the heater 4 based on the output signal of the temperature sensor 3, controls the temperature of the photosensitive drum 2, and paints the photosensitive drum 2. The photosensitive drum 2 is immersed in a coating liquid in a tank 5, and the coating liquid is applied to the outer peripheral surface of the photosensitive drum 2 by a dipping method.
塗布処理後、感光ドラム２を塗料タンク５より引上げて
加温ヒータ４により、感光ドラム２の外周面に成膜され
た感光体層の乾燥工程を行う。After the coating process, the photosensitive drum 2 is pulled up from the paint tank 5, and the photosensitive layer formed on the outer peripheral surface of the photosensitive drum 2 is dried by the heater 4.

る。As explained above, in the present invention, eight heating heaters are placed inside the photosensitive drum, and by controlling the temperature of the photosensitive drum using the heating heaters, even paints using high boiling point solvents can be coated using the dip coating method. Since the photosensitive drum is heated, the coating liquid dries quickly and a thick film can be formed. This prevents concentration changes due to solvent volatilization.
, high boiling point solvents that do not require concentration adjustment can be used.
